Physics Academic Software Ceases Operations

After
22
years of offering author written software to the physics teaching
community, Physics Academic Software ceased operations May 31,
2011. Many of the programs no
longer run on current computers and many physics applications can now
be used
directly from the web.

Please
check with comPADRE Digital Librarysponsored by
The
American Association of Physics Teachers to see if the program you are
looking for is offered there.
